Yes.

I tell the browser to check for freshness on page load. I expect that 
the resource is cached in the current instance (before any new page 
refreshes occur). So, yes, I expect it to be cached on any subsequent 
request before a page request, but no, I expect it is not cached on any 
subsequent refresh.

That's just it.. is saving image data before a page refresh occurs 
considered "caching"?
